Application filed August 18, 1923. Serial na-ssawa To all whom it may concern:

Be it known that I, JACOB L. SHROYER, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grids for Gas- Burning Broilers, of which the following is a specification.

This invention relates to grids for gas burning broilers.

One of the objects of the invention is to improve broiler grids.

Another object is t improve the efliciency of grids and the gas burner used therewith.

A further object is to prevent the gases of combustion from contaminating the food being broiled by carrying thev products of combustion away thru a flue at the same time permitting the flame to: be and remain unconfined to promote combustion.

A further object is to provide means to prevent the flame at the burner from reaching the food being cooked.

Other objects and advantages will hereinafter appear from a consideration of the following description when taken in conjunction with the drawings, wherein F '1 is a plan view of the grid, showing parts in section. r

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a section on line 33 of Fig. 2.

In all the views the same reference characters are employed to indicate similar parts.

The grid, as shown, comprises a one-piece casting consisting of a series of inverted parallel, relatively deep, open channel members 5 and transvers'ely-extending connecting bars 6 leaving rectangular openings 7. The food to be broiled is placed directly upon the upper surface of the bars, and not upon the channel members. By placing the bars above the channel members and placing the food directly on'the bars and not upon the parts upon which the flames impinge a more uniform distribution of heat is accomplished by conduction of the heat from the channel members to the bars.

Each channel opening 8 is in communication with a flue 9 to which may be connected a stack 10.

There are as many gas burners 1]. as there are channel members, and each burner projects into the channel 8, as at 12. The burners are connected to a common supply pipe 13 and are separately controlled by a han' dle 14.

' The burners are located near the topof the channels and the flame is forcibly projected into the channels.

The channels being open at the bottom combustion is economically promoted by free entrance of oxygen and the heat engendered"by the projected flames is conveyed thereby along the channels and dispersed or conducted to the integral cross bars 6. V

The supply pipe 13 is supported on brackets 15 secured to the grid.

\Vire cloth strips 16 may be placed between the upper surface of the cross bars 6 and the open side of the channel members to prevent possibility of a flame touching the under side of the food on the bars 6.

The juices from the food will pass thru the openings 7 and the meshes of the cloth 16, should the cloth be used, into a suitable receptacle that may be placed below the grid. The strips of wire cloth may be easily removedfor cleaning or replacement.

In the use of grids where the food is supported directly on the intensely heated surfaces upon which the flame impinges portions will be overdone or burned, while intermediate portions will remain underdone or rare. 7

In the structure herein the heat applied to the grid is uniformly distributed throughout the structure by conducting the heat from the primarily, intensely heated channel members to the food supporting bars, and the food is cooked by radiant heat from said members instead of by direct contact with the most intensely heated portions thereof.

Having described my invention what I claim as new and desire to secure by Letters Patent, is H 1. A broiling grid and burners comprising a series of inverted, parallel, open channel members; a flue with which the openings in all the channels communicate; a series of transversely-extending bars connecting the channels and providing a broiling surface and a burner for each channel arranged to project a flame directly into each channel.

2. A broiling grid and burners comprising a series of inverted, parallel, open, deep channel members; a flue into which said channels open; a series of transversely-extending, integral, spaced, parallel bars providing a broiling surface above the channel members and a burner for each channel extending thereinto, near the top thereof, to project a flame thru the channel,

3. A broiler grid comprising a series of parallel, spaced, inverted channel members; a series of parallel, spaced bars in a com- 10 mon horizontal plane, extending transversely of said members, and connecting said members, With their upper surfaces above the members to provide a broiling surface, and gas burners, one extending into one end of each channel to project flames thru the channels and means to control each flame.
